Microhabitats are associated with bacterial and archaeal community structure in acid mine drainage from an abandoned mine

Acid mine drainage (AMD) is a severe environmental problem and a heterogeneous low-pH ecosystem containing diverse microbial communities. Microbial community structure across visually distinct AMD microhabitats remains poorly understood, particularly in South Korea, where field-b...

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poo...

Antiviral activity of Cirsium japonicum var. spinossimum extract and its flavonoid cirsimaritin against human coronavirus OC43

Coronaviruses cause a wide range of diseases, ranging from the common cold to severe illnesses such as COVID-19. Although vaccines and therapeutics against COVID-19 have been developed, recent reports have documented the emergence of viral variants with reduced susceptibility to...

JuRa: The Juventas Radar on Hera Mission to Probe Internal Structure of Didymos and Dimorphos Asteroids

Abstract JuRa, the Juventas Radar, is the sounding radar of the Hera/ESA mission on cruise to the asteroid Didymos and its moon, Dimorphos. In 2027, it will, for the first time, do direct observation of the internal structure of an asteroid for the benefit of both science and pla...

Integrated physical property measurements of titanium-bearing and host rocks for mineral exploration

Titanium is a critical mineral whose growing demand requires efficient methods for resource characterization and exploration. This study presents integrated physical property measurements of titanium-bearing ores and associated host rocks from the Myeonsan titanium ore deposit, S...

Development and application of a two-dimensional numerical model for debris flow-induced impulsive wave considering debris flow erosion-entrainment process

Landslides and debris flows occurring in reservoir watersheds can generate tsunami-like waves by inflowing into the reservoir. When such disasters occur during periods of high-water levels, such as the flood season, overtopping due to waves is inevitable. Analyzing such events is...

Improving the representativeness of unsaturated hydraulic parameter estimation using repeated drainage–imbibition tests

Water movement in the vadose zone plays a critical role in groundwater recharge, contaminant transport, slope stability, and landfill performance. However, the determination of unsaturated hydraulic properties remains challenging because estimated parameters are highly sensitive...

Random-noise denoising for turnaround-fibre DAS-VSP data via the Noise2Noise framework

Summary In this study, we develop a deep learning-based approach for denoising raw distributed acoustic sensing (DAS)-vertical seismic profiling (VSP) data. The data were acquired using vibroseis sources at borehole sites in Dangu-ri and Janghang-ri, Gyeongju, Republic of Korea....

A Data‐Driven Review of Geoscience Research Evolution Using SciBERT ‐Based Topic and Network Analysis

ABSTRACT This review provides a data‐driven synthesis of the evolution of geoscience research from 2004 to 2023. A field‐level bibliometric overview of 439,680 records indexed in the Web of Science Core Collection (Geosciences, Multidisciplinary) characterises broad publication p...

Chemical composition of granitic rocks and constituent minerals in the Eumseong Basin and adjacent areas, South Korea: Implications for weathering and groundwater chemistry

Abstract The chemical composition of bedrock and rock-forming minerals can influence both rock weathering characteristics and groundwater chemistry through water–rock interaction. Although plagioclase and biotite have both been widely studied in relation to these processes, detai...

Desorption-ControlledSelective Lithium Enrichmentfrom Spodumene Leachate Using H2TiO3 Adsorbent

Abstract The increasing demand for lithium has intensified the need for efficient lithium recovery processes. In this study, a selective adsorption–desorption strategy for selective lithium enrichment from spodumene leachate was developed using an H2TiO3 adsorbent. The adsorption...
